HIV and its associated factors among people who inject drugs in Mizoram, Northeast India

Mortality among HIV-Positive and HIV-Negative People Who Inject Drugs in Mizoram, Northeast India: A Repeated Cross-Sectional Study (2007-2021)

Background: HIV and drug overdose continue to be the leading causes of death among people who inject drugs (PWID). Mizoram, a small state in the northeast of India, has the highest prevalence of HIV in India and a high HIV prevalence among PWID. Objective: To estimate the mortality among HIV-positive and HIV-negative PWID and to describe its associated factors. Methods: Cross-sectional datasets from the 2007-2021 Mizoram State AIDS Control Society (MSACS) data comprising 14626 PWID were analyzed. Logistic regression analysis was conducted to examine the factors associated with mortality among HIV-negative and HIV-positive PWID after adjusting for potential confounding factors. Results: Mortality among HIV-negative PWID declined by 59% between 2007 and 2021. The mortality rate among HIV-positive PWID also declined by 41% between 2007 and 2021. The multiple logistic regression analysis revealed that being divorced/separated/widowed (AOR = 1.41, 95% CI 1.03-1.94) remained positively associated with mortality among HIV-positive PWID. Mortality among HIV-negative PWID remained positively associated with ages of 24-34 years (AOR = 1.54, 95% CI 1.29-1.84) and above 35 years (AOR = 2.08, 95% CI 1.52-2.86), being divorced/separated/widowed (AOR = 1.28, 95% CI 1.02-1.61), and the sharing of needles/syringes (AOR = 1.28, 95% CI 1.34-2.00). Mortality among HIV-negative PWID was negatively associated with being married (AOR = 0.72, 95% CI 0.57-0.90), being employed (AOR = 0.77, 95% CI 0.64-0.94), and having a monthly income. Conclusions: The mortality rate among HIV-negative and HIV-positive PWID declined significantly between 2007 and 2021 in Mizoram. To further reduce mortality among PWID, interventions should target those sharing needles/syringes, those above 24 years of age, and unmarried participants.

HIV, hepatitis B & C in people who inject drugs in India: A systematic review of regional heterogeneity & overview of opioid substitution treatment

BACKGROUND OBJECTIVES

This systematic review evaluates the human immunodeficiency virus (HIV), hepatitis C virus (HCV) and hepatitis B virus (HBV) burden among people who inject drugs (PWIDs) in India. In addition, we selectively examined research on opioid substitution treatment (OST)-related services due to their role in antiviral treatment uptake and adherence.

METHODS

Data were sourced from peer-reviewed and government publications between 1991 and September 20, 2023, searched in MEDLINE, Scopus and EBSCOhost. English language studies reporting weighted prevalence or raw numbers and recruitment sites were included for review. Quality was assessed using the Joanna Briggs Institute tool. Data synthesis was done in graphs and tables.

RESULTS

We included 50 reports, yielding 150 HIV, 68 HCV and 24 HBV prevalence estimates across India, revealing significant regional heterogeneity. Notably, 16 States had a single community-based HIV estimate, and 19 States had limited or no HCV data. The highest HIV and HCV prevalence was in Manipur (74.7% and 97.5%, respectively) in 1996. Recent spikes included 50.2 per cent HIV prevalence in Punjab (2010) and 73 per cent HCV in Uttar Pradesh (2021). Nationally, OST coverage in 2020 was under five per cent, with some northeast, north and central States exceeding this, but most others were falling below two per cent. No studies on the cost-effectiveness of directly observed treatment models for OST were identified.

INTERPRETATION CONCLUSIONS

There is a lack of sufficiently granular and generalizable estimates for HIV prevalence and any estimates for HCV and HBV among PWIDs in large parts of the country. Community-based representative studies are required to quantify the prevalence and severity of these diseases and allocate resources.

High Diversity and Transmission Dynamics of HIV-1 Non-C Subtypes in Bangladesh

Genetic diversity and molecular epidemiology of HIV are directly relevant to HIV transmission. We report here the genetic diversity and transmission dynamics of non-C subtypes of HIV-1 strains detected in Bangladeshi key populations. Sequence analysis of gag gene revealed four subtypes A1, B, D, G, and nine CRFs (01_AE, 02_AG, 09_cpx, 10_CD, 15_AE/B, 13_cpx, 14_BG, 22_01_A1, and 25_AGU). Most of these non-C strains were detected in returnee migrant workers from different parts of the world. Phylogenetic analysis showed that the Bangladeshi HIV-1 strains detected in migrant workers and their wives and local sex workers shared common ancestries. The identification of the multiple subtypes indicates high diversity of non-C HIV-1 variants circulating in Bangladesh which might have been imported by migrant workers from multiple geographical areas.

Finding a way forward with the community: qualitative inquiry in the generalized HIV epidemic in Mizoram, India

Introduction

Mizoram, the northeastern State of India bordering Myanmar, is presently witnessing a burgeoning generalized HIV epidemic along with the highest State-level HIV prevalence among female sex workers (FSWs, 24.7%) and people who inject drugs (PWID,19.8%) in the country. The present study was conducted against such background to understand the current situation of HIV prevention and care services in Mizoram, and capture community voices as well as concerns so that the way forward could be informed appropriately.

Methods

The study period was October through December 2020 (in the midst of COVID-restrictions) in the districts of Aizawl, Mamit, Kolasib, Lunglei, and Champhai where HIV prevalence crossed 1% among ante-natal clinic (ANC) attending women. Contrastingly, the national average HIV prevalence among ANC attendees is 0.24%, which formed the basis for selecting the aforementioned five high burden districts for this current inquiry. In-depth-interviews were conducted with community members and youth leaders, vulnerable and general population groups as well as HIV-program officials. Interviews were recorded, transcribed, translated and later coded for analysis following thematic approach.

Results

The emerging issues were grouped in three thematic layers; (1) HIV vulnerability, (2) challenges pertaining to prevention and care services, and (3) program elements and future roadmap. Discrimination at the community level, unfriendly behavior of some of the HIV-service staff, occasional interruption in supplies of anti-retroviral treatment and sterile syringes and needles were voiced as deterrents to accessing HIV prevention and care services by the participants. Community engagement, based on restorative approach rather than retribution and ensuring enhanced performance of the district AIDS program control units emerged as necessary programmatic elements.

Conclusion

This inquiry highlighted macro-social and structural forces contributing to stigma and discrimination toward people at risk of HIV. It is urgent that HIV-services are re-aligned through de-centralized district level innovations and creation of safer spaces at the physical, societal and familial level. These, even during the time of stress such as a pandemic, would help health services to remain resilient. HIV outreach, sensitization of the community leaders and health-care professionals through strategic communication and ownership of the communities in these endeavors appeared paramount.
